Yes alpha is positive, because it is a helium nucleus - 2 protons and 2 neutrons, so there is a 2+ charge. 

The mass of beta is negligible - it's just an electron.

Gamma does not have mass - it's a wave not a particle. It's an electromagnetic wave.

thanks everyone :P

Alpha is 2+ mass 4 (Helium nuclues) and is highly ionising

Beta - is a normal electron and has a negative charge with a mass of 1/2000

Beta + is a positron (anti matter electron) and has the same mass as an electron but the opisite charge
